I'm sure a number of people have gotten upgrades but I wouldn't plan on it. If a LV room is important to you try the discount codes available and see if you can reserve one.
Yes - back on our honeymoon - DH and I got upgraded from GV to LG - with a view of the entire 7 sea's lagoon - we got to watch the fireworks and water parade every night - it was awesome!!!
No matter what - there is no such thing as a *bad room* at GF!!
